Any tinted lens from any decent manufacturer whether polarized or not will be UV coated and probably 100% of polarized lenses from good manufacturers are coated.
I can't comment on Oakley's history as I don't pay much attention to OEM lenses as I have to replace them with my Rx. That they might not have been sufficiently coated for UV protection would have been a cause for concern. That they weren't (and still aren't necessarily) polarized isn't a big deal.
Omega is actually correct that the material of the lens plays a part in UV blocking. Glass will block a greater percentage of UV light than plastic so the coatings are even more important on plastic lenses.
Do this for fun if you are interested: take an old pair of polarized sunglasses and pop one of the lenses out (don't hold me responsible for damage!). Hold the one lens in front of the other oriented in the same direction and look through. You can still see through it, though darker because of the extra tint. Now rotate the lenses so that they are offset by 90 degrees. The combo will go completely opaque. One lens is blocking all of the light traveling along one axis and the other lens blocks light on the other axis. So, literally, a polarized lens BLOCKS light whereas a standard tinted lens attenuates light. But, it is not the amount of light that reaches your eye that causes damage to the eye, it is the type of light and you want to block as much, if not all, UV light from reaching your eye.
